Hello eveyrone, It turns out that in two occasions I have failed to commit my changes to the web site pages, and the Mono 0.10 runtime release actually points to the 0.9 release. If the downloaded package for Mono is not `mono-0.10.tar.gz', you have the wrong version. The correct url is: http://www.go-mono.com/archive/mono-0.10.tar.gz I apologize for the trouble. Miguel.
